基组加上极化函数，去掉不需要的弥散函数，重跑。否则即使收敛了结果也不能用。
仔细阅读http://sobereva.com/336了解基组方面的常识

太感谢了！！！我更改成这样可以用了吗？
%mem=1GB
%chk=D:\gauss\fuhe.chk

Cl上还是需要带弥散函数的，因为是阴离子。这就是为什么我说去掉”不需要“的弥散函数，个别必要的弥散函数还是得有
初始结构不合理，很多氢离得太近了，先用分子力场（UFF、MM2等）初步优化一下才能用DFT优化
此外必须加色散校正，必须加溶剂，必须做构象搜索

帖子标题不得乱用叹号，置顶的新社员必读贴以及http://bbs.keinsci.com/thread-9348-1-1.html都明确说了。这次给你改了，下次乱用叹号直接删帖扣分处理。

如置顶的新社员必读贴、论坛首页的公告栏、版头的红色大字非常明确所示，求助帖必须在帖子标题清楚、准确反映出帖子具体内容，避免有任何歧义和含糊性，仔细看http://bbs.keinsci.com/thread-9348-1-1.html。我已把你的不恰当标题 “Gaussian结构优化求助！！！” 改了，以后务必注意！

带上#P便于监控SCF收敛情况
体系多达近200个原子，已经算大体系了，绝对别用性能普通的个人电脑以及windows版Gaussian计算，否则耗时不极高才怪。如果你只有普通个人电脑可用，只有半经验级别的方法才能算得动。如果非要用普通PC做DFT，不仅耗时极高，再加上以你当前对量子化学的还没入门程度的了解，折腾2个月恐怕都优化不完。
对优化目的2d没必要，d足矣，本来体系就大

当前各种硬伤太多，强烈建议系统性学学再做计算，否则以后还要踩无数坑、白浪费无数时间
